Cube root. In mathematics, a cube root of a number x is a number y such that y3 = x. All nonzero real numbers have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8, denoted , is 2, because 23 = 8, while the other ...
512 is a power of two: 2 9 (2 to the 9th power) [1] and the cube of 8: 8 3. [2] It is the eleventh Leyland number. [3] It is also the third Dudeney number. [4] It is a self number in base 12. [5] It is a harshad number in decimal. It is the cube of the sum of its digits in base 10. [6] It is the number of directed graphs on 3 labeled nodes. [7]
Square root. Notation for the (principal) square root of x. For example, √ 25 = 5, since 25 = 5 ⋅ 5, or 52 (5 squared). In mathematics, a square root of a number x is a number y such that ; in other words, a number y whose square (the result of multiplying the number by itself, or ) is x. [1] For example, 4 and −4 are square roots of 16 ...
Using this notation for a three-layer cube is more consistent with multiple-layer cubes. [7] Rotating the whole cube: The letters x, y and z are used to signify cube rotations. x signifies rotating the cube in the R direction. y signifies the rotation of the cube in the U direction. z signifies the rotation of the cube on the F direction. These ...
Doubling the cube, also known as the Delian problem, is an ancient [a][1]: 9 geometric problem. Given the edge of a cube, the problem requires the construction of the edge of a second cube whose volume is double that of the first. As with the related problems of squaring the circle and trisecting the angle, doubling the cube is now known to be ...
The trail runs parallel to State Route 507 and intersects with the southern end of the Chehalis Western Trail. Trailheads are located at the trail termini in Yelm and at Tenino's City Park, with additional parking lots and entry points along the trail. [2] Rainier straddles the trail approximately 8.5-mile (13.7 km) east of Tenino. [3]

Cube (algebra) y = x3 for values of 1 ≤ x ≤ 25. In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 23 = 8 or (x + 1)3. The cube is also the number ...
